Issues in development of space-based solar power

Abstract

Space-Based Solar Power-SBSP) is a concept that has considerable potential to provide clean renewable energy. Increased population coupled with reduced natural resources represent a challenge to national and world security. The SBSP concept is to collect energy from the Sun in Earth orbit. The electrical energy is converted to microwave frequency for transmission to the surface of the Earth. There it is converted back in to electricity for use. Possible usages are base-load power, fuel conversion or direct delivery to consumers in isolated locations. The available potential of solar energy is greater than energy in petroleum reserves. The primary issue is defining the path to development of SBSP capability.
